Patients treated by Welsh (UK) hospitals for upper gastrointestinal (GI) bleeding were 41% more likely die if they were admitted on a public holiday and 13% more likely if it was at the weekend, according to research in the January issue of Alimentary Pharmacology and Therapeutics. Researchers who analysed the records of 22,299 people admitted a total of 24,421 times between 1999 and 2007 also found that admissions, but not death rates, were significantly influenced by social deprivation. "The higher death rates for weekend and public holiday admissions could not ...

What algorithms should an air defense system work with? Particle swarm algorithms if there are ten targets to be hit. If there are more than ten targets, greedy algorithms work best. These findings are presented by researcher Fredrik Johansson at the Informatics Research Centre, University of Skövde, in Sweden. So-called TEWA systems (Threat Evaluation & Weapon Allocation) are used to protect strategic targets from enemy attacks, such as an airfield that needs to be protected from incoming missiles. The systems discover threats, evaluates the threats, and aims the defender's ...

Georgia, US - A team of Bioengineers in the United States have modified a strain of bacteria to increase its ability to produce ethanol. The research, published in Biotechnology and Bioengineering, reveals how adaptation and metabolic engineering can be combined for strain improvement, a positive development for the biofuel industry. The team focused their research on Zymomonas mobilis, a bacterium noted for its bio-ethanol producing potential. However, the team believed that ethanol production could be increased through improvement of xylose fermentation. "Zymomonas ...

College students whose parents have remained married to each other are faring better financially than their peers with divorced or remarried parents, according to new research from Rice University and the University of Wisconsin. The study, published in the December Journal of Family Issues, found that divorced parents contributed about a third of what married parents contributed to their children's education even though the divorced parents' incomes are about half as much as their married peers'; remarried parents contributed about half of what married parents contributed, ...

Halting the growth of melanoma tumors by targeting the MIC-1 protein that promotes blood vessel development in tumors may lead to better treatment of this invasive and deadly cancer, according to Penn State College of Medicine researchers in The Foreman Foundation Research Laboratory. "Preventing vessels from developing in tumors is one way to stop them from growing," said lead author Gavin Robertson, Ph.D., professor of pharmacology, pathology, dermatology and surgery. "However, the identity of the proteins secreted by tumors cells enabling the angiogenesis process to ...

When it comes to health care blue lights, are usually most useful on the top of ambulances but now new research led by the University of Warwick has found a way to use blue light to activate what could be a highly potent platinum-based cancer treatment. Research led by the University of Warwick, along with researchers from Ninewells Hospital Dundee, and the University of Edinburgh, have found a new light-activated platinum-based compound that is up to 80 times more powerful than other platinum-based anti-cancer drugs and which can use "light activation" to kill cancer ...

Watching a television show from a digital video recorder (DVR) gives viewers a chance to skip commercials, but new research finds that owning a DVR does not influence the demand for advertised products despite its ad-skipping feature. In fact, only a small percentage of ads were fast-forwarded by DVR users who participated in the study, and even that did not have an adverse effect on sales. The research was conducted by Jean-Pierre Dube from the University of Chicago Booth School of Business, Bart Bronnenberg from Tilburg University in The Netherlands and Carl Mela ...

WORCESTER, Mass. – A research team at Worcester Polytechnic Institute (WPI) has demonstrated the feasibility of a novel technology that a surgeon could use to deliver stem cells to targeted areas of the body to repair diseased or damaged tissue, including cardiac muscle damaged by a heart attack. The technique involves bundling biopolymer microthreads into biological sutures and seeding the sutures with stem cells. The team has shown that the adult bone-marrow-derived stem cells will multiply while attached to the threads and retain their ability to differentiate and grow ...

Runners who continue running when they are exhausted unknowingly change their running form, which could be related to an increased risk for injury. A study by Tracy Dierks, assistant professor of physical therapy at Indiana University, found that toward the end of a normal running session, runners generally displayed an increase in motion in their hips, knees and ankles. "Our study showed that at the end of a normal run, when they were getting tired, their mechanics were beginning to change," Dierks said. "When you notice fatigue, you're most likely putting yourself ...

Rice University researchers have moved a step closer to creating robust, three-dimensional microbatteries that would charge faster and hold other advantages over conventional lithium-ion batteries. They could power new generations of remote sensors, display screens, smart cards, flexible electronics and biomedical devices. The batteries employ vertical arrays of nickel-tin nanowires perfectly encased in PMMA, a widely used polymer best known as Plexiglas. The Rice laboratory of Pulickel Ajayan found a way to reliably coat single nanowires with a smooth layer of a PMMA-based ...

Over a 14-week period, the children who had the greatest exposure to Jalan Sesama improved significantly in literacy, mathematics, early cognitive skills, safety knowledge and social awareness, compared to those with no or low exposure to the program. The study is available online in advance of publication in the International ...

COLLEGE STATION, Dec. 9, 2010 – Changes in clouds will amplify the warming of the planet due to human activities, according to a breakthrough study by a Texas A&M University researcher. Andrew Dessler, a professor in the Department of Atmospheric Sciences, says that warming due to increases in greenhouse gases will cause clouds to trap more heat, which will lead to additional warming. This process is known as the "cloud feedback" and is predicted to be responsible for a significant portion of the warming over the next century. Dessler used measurements from the Clouds ...

WASHINGTON — A new National Research Council report finds no scientific basis that more stringent testing of meat purchased through the government's ground beef purchase program and distributed to various federal food and nutrition programs -- including the National School Lunch Program -- would lead to safer meat. The U.S. Department of Agriculture's Agricultural Marketing Service (AMS) buys ground beef from suppliers who must meet mandatory process, quality, traceback, and handling controls as well as comply with strict limitations on the amounts of bacteria in the ...

COLUMBUS, Ohio – A preliminary look at an ice field atop the highest mountain in the eastern European Alps suggests that the glacier may hold records of ancient climate extending back as much as a thousand years. Researchers warn, however, that the record may soon be lost as global warming takes its toll on these high-altitude sites, according to a new study in the Journal of Glaciology. The glacier, Alto dell'Ortles, is the highest large ice body in the eastern Alps, reaching an altitude of 12,812 feet (3,905 meters) above sea level. It is small, though, measuring ...

ANN ARBOR, Mich. — The risk of esophageal cancer among patients who suffer from gastroesophageal reflux disease (GERD) is not as high as many may think, according to new research from University of Michigan gastroenterologists. GERD is considered a relative risk for developing esophageal adenocarcinoma, but the absolute risk is not known, says Joel Rubenstein, M.D., M.Sc., an investigator with the Department of Veterans Affairs Center for Clinical Management Research in Ann Arbor and Assistant Professor in the University of Michigan's Department of Internal Medicine. "Since ...

New clinical strains of cholera appear to have evolved a distinctly different mechanism to cause the same disease according to research published in the current issue of the online journal mBio®. Vibrio cholerae is the causative agent for the diarrheal disease cholera. While there are more than 200 different serogroups only the O1 and the O139 strains have been known to cause epidemic and pandemic outbreaks of disease, using a toxin-coregulated pilus (TCP) and cholera toxin (CT), which other strains lack. "While non-O1, non-O139 strains have caused sporadic disease ...
